* Added crew_profile as an optional package.

Does support bash, zsh, and fish, but not all 3 at the same time.

* Added end keyword. Oops!

* Make #{CREW_PREFIX}/etc/profile a symbolic link to ~/.profile

* Does not overwrite previously set configuration.

Creates symlink from #{HOME}/.profile to #{CREW_DEST_PREFIX}/etc/profile

Has postinstall that works with 3 shells.

* Fix fish syntax

* Changed #{HOME} to $HOME

* Changed crew_profile.rb to correlate with the crew version

* Changed version number to 1

* Changed $HOME back to #{HOME}

* Solved $HOME not being defined. Changed some things.

* Falling back to what works. Also added .lightblue to 'touch ~/.profile'

* Uses #{ENV['HOME']} at @uberhacker's requests instead of using hacky workarounds.
